Seven Hermetic Letters is a course of instruction for the higher development of the spirit and the mysterious powers of the soul. The exercises in this book are organized in such a way that the novice can progress without the benefit of a teacher (a guru), and the advanced student in Hermetics will find many missing links in the practice of the holy art of Hermetics. These letters by Dr. Georg Lomer are undoubtedly some of the best and most basic exercises for the attainment of higher knowledge and ultimate wisdom. An excellent basic precursor to the Franz Bardon system of universal magic.
